EulerOS 2.0 SP2 : kernel (EulerOS-SA-2017-1155)
high Nessus Plugin ID 102242
Synopsis
The remote EulerOS host is missing multiple security updates.Description
According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :- An issue was discovered in the size of the stack guard page on Linux, specifically a 4k stack guard page is not sufficiently large and can be 'jumped' over (the stack guard page is bypassed), this affects Linux Kernel versions 4.11.5 and earlier (the stackguard page was introduced in 2010).(CVE-2017-1000364)
- The make_response function in drivers/block/xen-blkback/blkback.c in the Linux kernel before 4.11.8 allows guest OS users to obtain sensitive information from host OS (or other guest OS) kernel memory by leveraging the copying of uninitialized padding fields in Xen block-interface response structures, aka XSA-216.(CVE-2017-10911)
- Multiple race conditions in the ext4 filesystem implementation in the Linux kernel before 4.5 allow local users to cause a denial of service (disk corruption) by writing to a page that is associated with a different user's file after unsynchronized hole punching and page-fault handling.(CVE-2015-8839)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
